The CRAFTSMAN Standard Wall Vac Filter for wet/dry vacs is designed to be a replacement filter for most Shop-Vac branded wall vacs. It is designed for pick-up of everything from dirt and sawdust to jobsite debris or general build-up in your car or truck. For added convenience, the shop vac filter material can be washed with water and reused after properly drying. Be sure to consult your owner's manual for additional filtration and installation instructions. To ensure maximum performance of your shop vacuum cleaner, replace wet dry vac filters and dust collection bags regularly. This is not a product of, nor is it sponsored by Shop-Vac.
